Ok, I love #3 :thumbup:
I want to add my 2 cents. Make it a full 9.5 - 10 inch blade. To compare to all the other so called 10 inch bowies out there.
As for metal, although I do not make kives, I use and abuse them. I have broken 5160 knives much more so than A series knives. I think it has to do with the HT. I think that it is harder to get the HT right on 5160 just IMO.
My experience with 5160 is just the opposite of T1mpani. When 5160 has been ground to a cutting edge, it fails much easier than 3V or even 52100. I have broken good 5160 knives with hardly any trouble where my 52100 and A2 knives did not break. Of course this all depends on the maker as well.
My order of preference would be this:
A8, 3V, A2, S7, 52100 (pain to HT), W2, M4, L6, 5160
